Ceiling fans will make you feel cooler when you stand in a room where one is running, but they don’t actually cool the air in your home. They only make you feel cooler because by moving the air, it feels like a breeze is cooling your skin.
A ceiling fan that’s running in an unoccupied room is using electricity without doing any good. Turn off your ceiling fans when you leave a room, and flip them on when you come back in.
Do install ceiling fans, especially in rooms where your family tends to congregate. A ceiling fan will allow you to raise the thermostat setting about 4 degrees with no reduction in comfort.
